Question

Fill in the blank with the most appropriate option.
The teacher told us ____ any mistakes.

• A. don't make
• B. not make
• C. not to make
• D. not made

Answer 1

Answer: (C)

not to make

The normal form of a negative infinitive is "not to (verb)", in all contexts. The given context refers to 'make', so the correct usage would be 'not to make'. Hence Option C is the correct answer.
We use "don't" when the subject is I, you, we or they. Hence Option A is incorrect.
"Not make" and "not made" are grammatically incorrect as the adverb 'not' and the verb 'make/made' are being used without a preposition, which does not make the relationship between the two clear. Hence options C and D are incorrect.
